SHEET-METAL BUILDING CONSTRUCTION.

To all 'whom it may concern:

Be it known that I, JOHN B. GOODWIN, of Ambridge, in the county ofBeaver, State Of Pennsylvania, have invented a certain new and usefulImprovement in Sheet- Metal Building Construction, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

My invention relates to metallic building construction, moreparticularly to surface construction of flooring.

The invention is particularly adapted to the production of floor,shutter and stair construction.

I shall now describe my invention so that others skilled in the art towhich it appertains may understand and construct the same, referencebeing had to the accompanying drawings in which like reference numbersindicate like parts throughout different views.

Figure 1 is a perspective View; Fig. 2 is a top plan view of the sheetmetal plating; Fig. 3 is a sectional view on the line 3-3 of Fig. 2;Fig. 4 is a similar view on the line 4 4 of Fig. 1; Fig. 5 is a similarview on the line 5-5 of Fig. 4; and Fig. 6 is a sectional view showingmy invention as applied to the construction of a stair-tread.

In describing my invention, the reference numeral 2 indicates a seriesof thin metallic plates, provided with the openings 3.

The numerals 4 indicate spacing members formed preferably integral withthe plating. These spacing members are shown in the drawing as soformed, consisting of the continuous projecting wall 5 surrounding theopening 3.

The plates -2 are adapted to be placed together in the manner shown inFigs. l, 4, and 5, the openings 3 registering and the projecting walls 5contacting with one another. With the plates placed together in thismanner, the openings 3 are adapted to receive a suitable soft filler 6,which is adapted to not only bind the plates together, but also byreason of the head Jformation 7 presents Specification of LettersPatent.

Application led August 14, 1909.

Serial No. 512,923.

an anti-slipping surface, which is an important feature in floor,shutter and stairtread construction. This filler may be of any suitablecomposition. I find lead to be an admirable material for this purpose.It not only is easy of application and serves to effectually bind theplates together, but it may also be readily removed should it becomenecessary to replace worn plating. The distance of separation of theplating 2 is dependent upon the degree of projection given the spacingmembers 5.

The advantages of my invention will be appreciated by those skilled inthe art. The projecting walls 5 while serving as spacing means for theplates 2 also reinforce the construction, while the filler 6 not onlyserves as a connecting means for the plates but also provides ananti-slipping surface.

It will be apparent that changes may be made without departing from myinvention.

`Having thus described my invention, what I claim and desire to secureby Letters Patent is,-

l. The combination of a plurality of plates, openings formed therein,and means for binding the plates together, consisting of a soft filleradapted to occupy the openings.

2. The combination of a plurality of plates, openings formed therein,means for spacing the plates one from the other, and a filler occupyingthe openings and adapted to connect the plates together.

3. The combination of a plurality of plates, openings formed therein,means for spacing the plates one apart from the other, and comprising aboss surrounding the openings, and means for connecting the platestogether, comprising a soft filler adapted to occupy the opening andprovided with projecting head portions adapted to form an anti-slippingsurface.

In testimony whereof, I have hereunto set my hand.
